HoloLens' worst enemy is still itself

Two years ago at its Build developer conference, Microsoftunveiled HoloLens, a futuristic holographic headset it said would usher in future of computing: A "mixed reality" where the virtual blurs into the real world.

HoloLens looked extremely promising, except for one thing: Its narrow field of view meant using it wasn't anything close to the expansive and immersive experiences portrayed by its on-stage demos.

Fast forward to Build 2018, and the same problem continues to hold back the headset as well as Microsoft's entire mixed-reality platform.
